Put the seeds and pulp in a large bowl of water. Swish, scoop out the floating seeds and pick off any strings.
Bring 4 cups of water and 2 tbsp kosher salt to a boil. Add the seeds and simmer 10 minutes.
Drain and spread the seeds on a clean towel. Pat them very dry.
Toss the seeds with olive oil and 1/2 tsp salt. Spread them in a single layer on a rimmed baking sheet.
Roast 15 to 20 minutes, stirring halfway, until golden and they crackle when you stir them.
Cool on the pan; they get crunchier as they cool. Taste and add more salt if needed.
